Which characteristic would be most important when a scientist needs to study the changes in climate conditions over a five year period

I think the answer is observant since the scientist needs to really pay attention and look at all the details.

observant

Explanation:

The scientists must be observant. This is because of the fact that the observation involves the examination and monitoring something on the basis of different parameters such as shape, form, color, duration for accomplishment of a reaction and others.

If the scientists studies and observe the the climate pattern for a period of five years he must be able to identify the actual climate condition.

answer:

the water molecules are transferred from the roots to the stem or top parts of the tall tree because of important properties of water which are adhesion, cohesion and capillary action. cohesion is the property of water molecules keeps water molecules in a combined state by sharing of bonds between them at the atomic level. adhesion allows the interaction of water molecules with other substances or substrate. adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. capillary action occurs when the adhesive force to the vessel wall is stronger than the cohesive force between water molecules. capillary action mimics the transfer of water from a tube or pipe. in this way water utilizes its property to transfer water from down to top level of the plant.  

c) 50% there are four chromosomes. after crossing over, 2 of the four have been changed. that means any gamete has a 2 in 4 chance or 50% chance of receiving the mutated chromosome.
